Control apparatus, storage apparatus and computer-readable recording medium having stored therein control program

A control apparatus served as a first control apparatus includes a first information storage unit configured to store therein coupling information relating to a coupling relationship between a plurality of control apparatus and a plurality of devices, the plurality of control apparatus including the first control apparatus and controlling access to the plurality of devices, and a processor. The processor specifies, in response to a first access request to a first device from among the plurality of devices, a second control apparatus responsible for the first device based on the coupling information stored in the first information storage unit, and issues an instruction to access to the first device based on the first access request received by the first control apparatus to the specified second control apparatus through a relay apparatus that relays information to be transferred between the plurality of control apparatus.
